Application filed January 23, 1905. Serial No. 242,395.

To (if/ZZ 71172/0711, llt 'nt/,mj con/cern.'

Be it known that I, JoiIN J. Hasan, a citizen o'l the United States,residing at Beaver Crossing, in the county of Seward and State ofNebraska, have invented a new and usetul Traction-Coupler, of which thefollowing is a simple and convenient manner.

Another object of the invention to embody the same in such torni as topermit ol' it being mounted directly upon the tongue or draw-bar of theseparator and capable of adjustment longitudinally and laterally toaccommodate the device to the position el: the traction-engine withrespect to the separator. W'ith these and other objects in view thepresent invention consists in the combination and arrangement of parts,as will be hereinafter more fully described, shown in the accompanyingdrawings, and particularly pointed out in the appended claims7 it beingunderstood that changes inI the form, proportion, size, and minordetails may be made within the scope ofthe claims without departingYfrom the spirit orsacri'ficing any oi the advantages oi the invention.

Aln the accompanying drawings, Figure lv is a plan. view oi a couplermounted upon. the tongue or draw-bar oi a separator with the shiiitabledraw-bar member extended. Fig. 2 is adetail perspective view showing theshi'ltable draw-bar member 4swung to one side. Fig. 3 isa crosssectionalview on the line 3 3 of Fig. l. Fig. d is a sectional view on the lineLL 4 of Fig. l. Fig. 5 is aflragmentary detail plan view with theshi'litable drawbar member at its rear limit.

Lilie characters of reference designate corresponding parts in each andevery iligure of the drawings. n

As embodied in the accompanying drawings the present invention includesa stationary draw-bar member l, which ordimirily the tongue of aseparator and is preiu'ably formed of spaced longitudinal bars toproduce a longitudinal slot 2, said bars being connected at their'forward ends by bolts C3 and 4 and adjacent their rear ends by a bolt5. Suitable braces (i extend between the bar :members l and the 'lronttruck or axle of the separator, a portion oi.: which has been shown at7. longitudinallyslotted cross-head 8 is applied to the liront end otthe draw-bar and preferably consists of a metal bar bent to Aiorm anelongated loop with its extremities bent to produce ears orattaching-brackets tif applied to opposite sides oit the liront end olf'the drawbar and secured. thereto by the adjacent bolt l. A Viller memberQ, preferably a metal strap bent upon itself, is secured within the`forward end portion oill the slot 2 by means of the bolts 3 and il, theilront oilI the iiller member being formed into an eye l0, which isVprojected into the slotted,Crossherul, the Ylront of the latter beingbulged or bowed outwardly at ll to accommodate the eye l0. lNithin theslotted cross-head at each side of the eye l() there is avertically-swinging pivotal latch l2, which is pivoted intermediate otits ends, as at 13, there being a spring la secured within the adjacentouter end por tion ol` thecross-head and bearing againstthc short ortail end of the latch, so as to yieldably depress said end and elevatethe opposite longer end of the latchv above the top of the cross-head,there being a stop-pin or projection l5 carried by the cross-headbeneath the tail oi' the latch to limit thedownwail movement thereof.

The movable member oiV the draw-bar consists oll upper and lower `llatmetallic bars l and 1.7, which embrace the bar l and are connected attheir rear ends by a bolt 18,- working in the slot ot the stationarydraw-lun', the YI'ront ends of the bars being (ainnected by a bolt lf),whichlies in i'ront oll the cross-head. ln l'ront and rear ot the boltl0 the bar members ll and l7 are provided with ifi-gistered openings 2()and 2l tor the removalile reception ot headed pins 22 and 23, ol whichthe pin 25J is designed to engage the eye l() when the movable draw-barmember is at its rear limit. The ilorward adjustmeiit ol" the mov abledraw-bar is limited by Areason oll the bolt ltl contacting with the rearend of the filler E).

As clearly indicated in Figs. l, 3, and .5,

TOO

the upper part 16 of the movable draw-bar normally lies between theinner elevated ends of the latches 12, whereby the movable draw-bar isheld against lateral swinging movements upon the bolt 18 as a center;but either of these latches may be depressed below the upper bar member16, whereupon the movable draw-bar may be swung to either side of thestationary draw-bar, as clearly indicated in Fig. 2 of the drawings.

lt will of course be understood that either of the pins 22 and 23 may beengaged with the coupling element on the traction-engine when themovable draw-bar is extended; but when the movable draw-bar is at itsrear limit, as in Fig. 5, the pin 23 serves to hold the movable bar atits rear limit, and therefore the pin 22 only is capable of beingengaged with the coupling element of the traction-engine.

Having fully described the invention,what is claimed isA 1. Atraction-coupler comprising a fixed draw-bar, a shiftable draw-barmounted for endwise adjustment upon the fixed draw-bar, and a couplingdevice carried by the movable draw-bar.

2. A traction-coupler comprising a fLxed draw-bar, a shiftable draw-barmounted to swing transversely upon the fixed draw-bar, and latches todetachably hold the shiftable draw-bar in alinement with the fixed bar.

3. A traction-coupler comprising a fixed draw-bar having alongitudinally-Slotted cross-head at its forward end, a shiftabledraw-bar pivotally supported upon the fixed draw-bar to swingtransversely thereacross, and latches mounted within the slottedcrosshead for engagement with opposite sides of the shiftable draw-barto hold the same in alinement with the fixed draw-bar.

l. A traction-coupler comprising a fixed draw-bar, a shiftable draw-barmounted for endwise adjustment upon the fixed drawbar and capable ofswinging transversely thereon, and latches to detachably hold theshiftable draw-bar in alinement with the fixed bar.

5. A traction-coupler comprising a fixed draw-bar having alongitudinally-slotted cross-head at its forward end, a shiftabledraw-bar pivotally supported upon the fixed draw-bar to swingtransversely thereacross, and spring-pressed latches pivoted adjacenttheir outer ends within the slotted cross-head with their inner endportions yieldably elevated above the top of the cross-head and spacedto engage opposite sides of the shiftable draw-bar to hold the latter inalinement with the fixed draw-bar. l

6. A traction-coupler comprising a fixed draw-bar having a longitudinalslot, a member secured within the slot and provided with an eye, anendwise-shiftable draw-bar having a part working in the slot and limitedin its forward movement by the member in the slot, said shiftabledraw-bar having an opening for alinement with the eye, and a removablepin for engagement with the opening and the eye.

7. A traction-coupler comprising a fixed draw-bar having a longitudinalslot, a metal strap folded upon itself and secured within the slot, thebend of the slot being formed into an eye, an endwise-shiftable draw-barcomprising opposite members slidably embracing the fixed draw-bar andconnected by a fastening working in the slot of said fixed draw-bar, thestrap lying in the path of the forward movement of the fastening tolimit the endwise adjustment of the shiftable draw-bar, the shiftabledraw-bar members being provided with perforations for alinement with theeye, and a removable pin capable of engagement with the perforations andthe eye.

S. In a tractioncoupler, the combination of a longitudinally-slottedfixed draw-bar, a longitudinally-Slotted cross-head secured to the outerend of the draw-bar with the intermediate slotted portion of thecross-head in communication with the slot of the drawbar, a metal strapfolded intermediate of its ends and secured within the slot of thedrawbar, the bend of the strap being formed into an eye lying in theslot of the cross-head, spring pressed pivotal latches mounted withinthe slot of the cross-head at opposite.

sides of the eye with their inner free ends normally elevated above thetop of the crosshead, an endwise-shiftable draw-bar comprising spacedmembers slidably embracing the slotted portion of the fixed draw-bar,front andrear fastenings connecting the slidable draw-bar members, thefront fastening being in front of the cross-head and the rear fasteningworking in the slot of the fixed draw-bar, the rear end of the straplying in the path of the forward movement of the rear fastening, aremovable coupling-pin piercing the forward end portions of the slidabledraw-bar members in front of the front fastening, said draw-bar membersbeing provided with alined perforations for registration with the eye,and a removable pin for engagement with the perforations and the eye,the movable draw-bar capable of being swung across the fixed draw-barupon the rear fastening as a center and also capableof being held inalinement with the fixed drawbar by the latches.

In testimony that lv claim the foregoing as my own i have hereto affixedmy signature in the presence of two witnesses.
